Description

Impeller for exhaust gas turbocharger
Technical field
The present invention relates to a kind of impellers for exhaust gas turbocharger of preamble according to claim 1.
Background technology
Impeller for exhaust gas turbocharger is known.Impeller include for be arranged in exhaust gas turbocharger can Turbine in the exhaust gas guide section of percolation and for being arranged in the air guiding portion section of exhaust gas turbocharger to flow Compressor drum.Turbine and compressor drum are torsionally connected to each other by means of axis, and the axis is rotatably received within exhaust gas In the bearing section of turbocharger.Other intermediate member can be provided between compressor drum and turbine.
Therefore, in order to avoid lubricant is spilt into from bearing section in air guiding portion section, so-called disc, institute are equipped with Disc is stated to be arranged on the rotor back side of compressor drum.Disc is coaxially constituted on axis.Component it is antitorque Connection obtained by means of retaining element, the retaining element compressor drum on the end that rotor back side is constituted with axis Force-fitting and shape-ordinatedly connect.In general, retaining element is constituted in the form of nut.
Invention content
It is an object of the present invention to provide a kind of improved impellers for exhaust gas turbocharger.
The purpose is realized by the impeller for exhaust gas turbocharger of the feature with claim 1.Have The suitable and not universal improved advantageous design scheme of the present invention provides in remaining claim.
Impeller according to the present invention for exhaust gas turbocharger includes:Turbine;Torsionally connected by means of axis with turbine The compressor drum connect;And the intermediate member being arranged on axis between compressor drum and turbine.In order to improve exhaust gas turbine Allow work torque, at least one face of intermediate member and/or the third face of compressor drum and/or axis the 4th of supercharger Face has protrusion, the base portion in the face that the protrusion than opposite is arranged harder.Advantage is to carry in a simple manner High exhaust gas turbocharger allows work torque, and without expending ground change component geometry or costly making without carrying With other materials, the other materials has high or higher robustness compared with the existing technology.
In other words this is indicated, impeller according to prior art is used to improve the permission operation torque of impeller Material must have the higher robustness compared with so far, and/or interface between the component of impeller must increase, Whereby shape cooperation and the axial force of connection of force-fitting can improve harmlessly, so that the friction coefficient in component is smaller In the case of transmit required operation torque.
In a design scheme, protrusion is manufactured by means of laser.Whereby, it can targetedly cause fine Protrusion and corresponding surface texture.
Description of the drawings
Other advantages, features, and details of the present invention are obtained from the following description to preferred embodiment and with reference to the accompanying drawings Go out.Hereinbefore mention in the description feature and feature combination and hereinafter attached drawing description in mention and/or Feature and the feature combination being only shown in the accompanying drawings can be not only by the combinations that provide respectively but also in a manner of other combinations Using or be used alone, without departing from the scope of the present invention.The identical element of identical or function is assigned identical attached drawing Label.Unique attached drawing shows the region of the compressor drum in impeller of the impeller for exhaust gas turbocharger with vertical section In part.
Specific implementation mode
Fig. 1 shows the part of the impeller 1 for exhaust gas turbocharger 2 in vertical section.Impeller 1 is including axis 3 and not The turbine being shown specifically.Turbine be at least partially disposed on herein exhaust gas turbocharger be not shown specifically flow it is useless In the accommodation space of gas guide section.Exhaust gas guide section has at least one transfer passage not being shown specifically, via described The exhaust gas of internal combustion engine can be conveyed to accommodation space to be conveyed to turbine by transfer passage.Turbine is, for example, radial turbine Machine, wherein turbine are at least substantially radially become a mandarin by exhaust gas to which air inlet is impacted.By with gas inlet impulse turbine, Turbine and entire impeller 1 are rotated with the turbine around pivot center 4.Similarly, turbine may be so-called mixed-flow whirlpool The turbine of turbine, wherein in combined flow turbine, turbine radially and partly can axially or axially be become a mandarin.
Axis 3 is at least mainly disposed in the bear box of exhaust gas turbocharger not being shown specifically, and by means of not The bearing arrangement being shown specifically is rotatably supported in thereon around pivot center 4 relative to bear box.In order to drive impeller 1, turbine is torsionally connect with axis 3.
The compressor drum for the air guiding portion section of exhaust gas turbocharger not being shown specifically is torsionally connected with axis 3 5 so that compressor drum 5 is driven via turbine by means of axis 3.As a result, by means of compressor drum 5, it is conveyed to internal combustion engine Air can be compressed so that internal combustion engine can particularly effectively be run.
Compressor drum 5 is torsionally connected by means of force-fitting and shape cooperation connection with turbine.In general, axis 3 It is constituted one-piece with turbine.In order to cause antitorque connection, compressor drum 5 is shifted onto on axis 3 and by usually in spiral shell The retaining element 7 of female form is fastened with turbine, and the axis has in the shaft segment 6 for being structured to accommodate compressor drum 5 There is the less diameter compared in the remaining area.
At least one intermediate member 8 is usually provided between turbine and compressor drum 5.Intermediate member 8 is being shown It is constituted in the form of disc in embodiment.However, the intermediate member can also be configured to cod or two components It can be clamped between turbine and compressor drum.
In order to make will not to reach in air guiding portion section from the lubricant overflowed in bearing section, it is equipped with so-called disc 8, the disc is arranged on the rotor back side 9 of compressor drum 5.Disc 8 is on axis 3, i.e. to surround the side of the axis Formula is coaxially constituted.
In the operation of exhaust gas turbocharger, impeller 1 has very high rotating speed, and the rotating speed can cause leaf Relative motion between each component of wheel 3,5,8, as long as work torque is more than the fastening torque of impeller 1.
Allow work torque to improve, the first face 10 in the form of the anchor ring 10 of disc 8 is equipped with surface texture, institute The universal surface roughness that surface texture increases the first anchor ring 10 is stated, and there is higher robustness.In other words this is indicated, the One anchor ring 10 has protrusion, and the protrusion is harder compared with base portion, and constitute has protrusion on the base portion.Therefore, One anchor ring 10 has such as lower surface, and being constituted on the base portion on the surface has protrusion, and the protrusion is harder than base portion itself. This can be carried out in different ways, such as by means of cutting method.Preferably, the composition of protrusion is passed through sharp by means of laser Photo-structuring progress.
Allow work torque, other faces to continue to improve:In disc 8 anchor ring form, deviate from 10 structure of the first face At the second face 11, or anchor ring form contacted with disc 8, in rotor back side 9 third face 12, or with the second anchor ring 11 The fourth face 13 of anchor ring form contact, in axis 3 has protrusion.It should be noted that with protrusion anchor ring 10,11, 12,13 with following anchor ring 12,13,10,11 it is opposite be arranged, the base portion of the anchor ring is softer than protrusion.Therefore, solid in impeller Protrusion can be pressed into base portion when tight, be achieved in shape cooperation and force-fitting connection.
